COMPONENTS AND FUNCTIONS
| Component |
Function |
|
|---|---|---|
| Engine-A/T-ECU |
Generates a pulse signal proportional to vehicle speed (revolving speed of the transmission output gear). |
|
| Auto-cruise control-ECU |
Receives signals from the vehicle speed sensor and each switch, and uses a microprocessor to control all functions of the auto-cruise control. |
|
| Actuator system |
Drives the auto-cruise vacuum pump according to signals from the Auto-cruise control-ECU and adjusts the throttle valve to the set opening with the actuator. |
|
| Auto-cruise control switch |
"MAIN" switch |
Switch for cruise control power. |
| "SET/COAST" switch |
Vehicle speed is set with the "SET/COAST" switch and "RESUME/ACCELERATING" switch. |
|
| "RESUME/
ACCELERATING" switch |
||
| "CANCEL" switch |
Cancels the cruise speed setting |
|
| Cancel system |
Stop lamp switch |
Outputs a signal to cancel cruise control |
| Inhibitor switch |
||
| Throttle position sensor (TPS) |
Generates an analogue voltage proportional to throttle opening. |
|
| Diagnosis connector |
If the MUT-II/III is connected, the diagnosis code and input check code from the Auto-cruise control-ECU can be read. |
|
| Auto-cruise control indicator lamp |
It is included in the combination meter and illuminates when the auto-cruise control "MAIN" switch is "ON" position. |
